Akukhona nje kuphela ukuthi imishini yokuzijabulisa ephathekayo nemikhiqizo ephathwa ngesandla, kodwa futhi isetshenziswa emikhiqizweni eluhlaza, njenge-photovoltaic, PVs, EVEM (Electricalvehicle, EV), njll. Ngokungeziwe ekuvikelekeni, izindleko, nosayizi, isikhathi sokusebenza sebhethri siyakhuliswa futhi siyanwetshwa, futhi idizayini yesistimu yamandla ebhethri nayo ibaluleke kakhulu. Ngokukhula kobuchwepheshe bebhethri obusetshenziselwa ukushayela ukusetshenziswa okuphathekayo, khetha indlela efanele yokukhipha nokushaja ibhethri elishajekayo.

Lesi sihloko siqale sibuyekeza isu elijwayelekile lebhethri elifanele ukusetshenziswa okuphathekayo, bese sixoxa ngokuphathwa kwamandla kanye nedizayini yokuphathwa kwebhethri kusetshenziswa izindlela zokucubungula ezihlanganisiwe zanamuhla. Ubuchwepheshe bebhethri obubalulekile ubuchwepheshe bebhethri bungahlukaniswa kalula kube izigaba ezimbili: uhlobo olungakhokhiswa noluphinde lushajwe. Ibhethri elingashajwa lisetshenziswa ngemva kokusetshenziswa, elibizwa ngokuthi ibhethri elilahlwayo.

Amabhethri e-alkaline amabhethri ajwayelekile alahlwa ekhaya. Amabhethri ane-alkaline aphinde ashajwe ayatholakala futhi emakethe, kodwa hhayi ngaphakathi kwengxoxo yalesi sihloko. Amabhethri e-alkaline ajwayelekile ane-voltage entantayo ecishe ibe ngu-1.

5V ukuze 1.65V. I-voltage yegama ngu-1.

2V. I-voltage ekupheleni kokuphila imayelana ne-0.9V.

I-voltage ekupheleni kwempilo yebhethri ye-alkali eyodwa ingaba phansi njengo-0.7V-0.8V.

, Inemininingwane ngokuya ngomthwalo wamanje. Ithebula 1 libonisa ukucushwa kwebhethri le-alkali okuvamile. Okunye ukusetshenziswa kungasetshenziswa ekucushweni okuhlukahlukene, kuye ngephrofayili yomkhiqizo, izidingo zesistimu, izindlela ezikhona zokucubungula kanye nokubala kwamandla.

Isibonelo, ububanzi be-voltage yokusebenza yendlela ethile yokucubungula igundane le-photovoltaic engenantambo ingu-1.8V ukuya ku-3.2V.

Igundane lisebenzisa ibhethri le-alkaline elilungiselelwe uchungechunge olu-2 ukuze lisebenze kahle ngaphandle kwesilawuli esingeziwe samandla. Uma ufuna idizayini yegundane ehlangene kakhulu, amabhethri e-alkaline angu-2 AA / AAA angase angasebenzi. Kulokhu, ibhethri ye-alkali eyodwa ye-AA / AAA ingasetshenziswa ukunciphisa isikhala sokuhlala, kodwa i-voltage ikhuphukele ku-1.

8V ene-boost converter. Ithebula 1: Ukuqhathaniswa kokucushwa kwebhethri ye-alkaline Ibhethri elishajekayo libhekwa njengebhethri lesibili, futhi inani lamandla lingabuyiselwa esimweni sangempela ngaso sonke isikhathi uma lisetshenziswa kuze kuphele ukuphila kwebhethri. Leli phepha lizochazwa njengesibonelo ngebhethri ye-lithium ion (Li-ION), ibhethri ye-lithium polymer (i-Li-poly) namabhethri e-nickel-hydrogen (NIMH).

Amabhethri e-NiMH ayindlela enhle yebhethri ye-alkaline ngoba umumo wawo kanye ne-voltage yokusebenza kufana namabhethri e-alkaline. Okunye okungalungile kwamabhethri e-nickel hydrogen endabuko ukuthi izinga lokuzikhipha liphezulu (cishe u-20% ngenyanga, njengoba kuboniswe kuThebula 2), kodwa kukhona umkhiqizi ohamba phambili webhethri onqobe lobu buhlobo obunzima, uchungechunge lwayo lwebhethri ye-nickel-hydrogen oluqalisiwe lusebenza ezinyangeni ezingu-12 kamuva lugcinwe okungenani i-85% ye-capacitance. Ukubuyisela inani likagesi webhethri le-nickel-hydrogen kunokwelashwa okulula futhi okunezindleko eziphansi, kodwa ishaja eshumekiwe esebenzisa indlela yokushaja eyisikwe kabili (ecaciswe indawo yamanje yokushaja nendawo yokusebenza) izofinyelela ukusebenza okuphelele.

Indlela yokushaja eyisikwe kabili ihlanganisa izici zokukhuphuka kwezinga lokushisa kanye nesikhathi namandla kagesi ngokuhamba kwesikhathi (noma okungashintshiwe). Ithebula 2: Ukuqhathaniswa kwezakhiwo zamakhemikhali ebhethri Ibhethri ye-lithium-ion okwamanje ithathwa njengobuchwepheshe bebhethri obuvuthiwe, obusetshenziswe kakhulu kumaselula nasezimotweni, uma kuqhathaniswa neminyaka eyishumi edlule, ukusebenza okuphansi nokungcono. Lapho uklama amasistimu ebhethri ezigaba eziningi, ibhethri eline-voltage eyodwa yegama lingu-3.

I-6V inenzuzo enkulu, enganciphisa inani lamasegimenti ebhethri angu-2/3. Amabhethri e-lithium-ion ngekhwalithi nevolumu ephezulu amandla ayenza ifanelekele ukusetshenziswa okuphathekayo okuningi, njengezidlali zemidiya yomuntu siqu noma ama-headphone e-Bluetooth angenantambo. Nokho, ukunikeza amasekhethi okuvikela ukunciphisa izingozi (ezifana ne-overchard noma ukushisa ngokweqile) okungase kubangele amabhethri e-lithium ion.

Ibhethri ye-lithium-ion inokuphila kwesevisi ende (ingakwazi ukushaja izikhathi ezingu-500-1,000), uma ibhethri ishajwa nsuku zonke, kuyadingeka ukushintsha ngemva kweminyaka engu-12. Dala isistimu yokulawula amandla ebhethri ye-lithium-ion enengqondo izonweba impilo yebhethri futhi ithuthukise ukwethembeka kwalo lonke uhlelo. .
